pldd(1)                  General Commands Manual                 pldd(1)

NAME         top

       pldd - display dynamic shared objects linked into a process

SYNOPSIS         top

       pldd pid
       pldd option

DESCRIPTION         top

       The pldd command displays a list of the dynamic shared objects
       (DSOs) that are linked into the process with the specified
       process ID (PID).  The list includes the libraries that have been
       dynamically loaded using dlopen(3).

OPTIONS         top

       -?, --help
              Display a help message and exit.

       --usage
              Display a short usage message and exit.

       -V, --version
              Display program version information and exit.

EXIT STATUS         top

       On success, pldd exits with the status 0.  If the specified
       process does not exist, the user does not have permission to
       access its dynamic shared object list, or no command-line
       arguments are supplied, pldd exists with a status of 1.  If given
       an invalid option, it exits with the status 64.

VERSIONS         top

       Some other systems have a similar command.

STANDARDS         top

       None.

HISTORY         top

       glibc 2.15.

NOTES         top

       The command

           lsof -p PID

       also shows output that includes the dynamic shared objects that
       are linked into a process.

       The gdb(1) info shared command also shows the shared libraries
       being used by a process, so that one can obtain similar output to
       pldd using a command such as the following (to monitor the
       process with the specified pid):

           $ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" \
                   -ex "quit" -p $pid | grep '^0x.*0x'

BUGS         top

       From glibc 2.19 to glibc 2.29, pldd was broken: it just hung when
       executed.  This problem was fixed in glibc 2.30, and the fix has
       been backported to earlier glibc versions in some distributions.
